Definitions
- This invention relates to a pour spout fitment, a method in which the pour spout fitment is attached to packaging material, a combination of the pour spout fitment and the packaging material, and a method of opening the same.
- Some of these known fitments include pour spouts which are inserted on the insides of the cartons through holes formed through panels of the cartons, so that pouring rims of the pour spouts project outwardly through the holes and flanges of the pour spouts are sealingly attached to portions of the inside surfaces of the carton panels round the peripheries of the holes.
- Such pour spout fitments can instead be inserted through, and sealed round, holes through carton blanks from which the cartons will be formed, for example on a form-fill-seal packaging machine.
- these types of pour spout fitments are attached before the cartons are filled.
- pour spout fitments are applied to the outsides of the carton blanks or cartons, around pouring holes formed through the panels. It is known to attach these types of pour spout fitments to the cartons either before filling or after filling. It is conventional for pour spout fitments to be attached to packaging material in the form of a laminate consisting of paperboard coated on both faces with thermoplastics, particularly low density polyethylene (LDPE) . It is also conventional for the packaging material to include, to the inside of the paperboard, a gas barrier layer, such as aluminium foil or ethylene vinyl alcohol (EVOH) .
- LDPE low density polyethylene
- LDPE low density polyethylene
- the packaging material to include, to the inside of the paperboard, a gas barrier layer, such as aluminium foil or ethylene vinyl alcohol (EVOH) .
- US-A-4813758 discloses a plastics pour spout construction particularly adapted for longer shelf-life barrier paperboard containers, such as containers of the gable-top type, the interior surfaces of the containers being lined with a major barrier layer. A dispensing opening is formed through the paperboard and the major barrier layer extends across and covers this opening.
- the skirt When the cap is unscrewed from the spout, the skirt carries part of the overall barrier away from its normal position closing the opening, thus rupturing the overall barrier and permitting dispensing of the contents of the container.
- the dispensing opening is usually die-cut prior to extrusion of the minor barrier layer of LDPE onto the exterior surface of the paperboard and prior to the placement on the internal surface of the paperboard of the major barrier layer, which may be a single layer of, for example, "SURLYN", a metallic foil, polyethylene, or other material.
- the major barrier may be in the form of layers of two or more different materials.
- the inner end of the skirt is adhered to the external surface of the LDPE layer in the dispensing opening by means of heat and pressure.
- the pour spout fitment relies upon strong adhesion between the skirt and the LDPE layer and between the LDPE layer and the major barrier layer for opening of the dispensing opening upon unscrewing of the cap.
- Rupture of the overall barrier is effected not only by axially outward movement of the skirt, but also by the rotation of the skirt relative to the pour spout and the container upon the initial unscrewing of the screw cap.
- Re-closing of the container in the event that all of the contents have not been dispensed upon the initial opening, is effected by simply screwing the cap back on, although the barrier properties of the container are lost owing to the rupture of the overall barrier. The force required to rupture the overall barrier indicates to the consumer that the package has not been tampered with.
- the ruptured state of the overall barrier lends visual proof of tampering.
- the pour spout fitment should be applied to a container having an external layer of polyethylene, that layer may be omitted and some other adhesive then take the place of that layer for joining the major barrier to the inner edge of the skirt and for joining the pour spout to the paperboard wall.
- the screw cap may have its outer skirt omitted and, instead, interengaging screw threads be located between the inner skirt and the pour spout.
- EP-B-0328652 discloses a plastics pour spout fitment in which a pour spout either extends through a hole through a carton wall and has its flange sealed to the inside of the wall, or has its flange sealed to the outside of the wall around a pouring port sealed with a film. In the former case, the inner end of the pour spout is sealed with a film. Within the pour spout is a tubular plunger formed at its inner end with a ring of downwardly projecting teeth which are interrupted at two diametrically opposite locations. Various embodiments of the fitment are disclosed.
- the plunger has two camming faces arranged at an angular pitch of 180° and extending outwardly to the outer end of the plunger.
- the two camming faces co-operate with respective downwardly-directed camming faces formed around the outside of an inner skirt of a screw cap arranged to be screwed onto the pour spout.
- Ratchet teeth formed on the inner peripheral surface of the pour spout co-operate with ratchet teeth formed on the outer peripheral surface of the plunger so as to produce rotation of the plunger with the screw cap during screwing of the screw cap onto the pour spout, but so as to prevent rotation of the plunger with the screw cap upon unscrewing of the latter.
- US-A-5147070 discloses a pour spout fitment in which a screw cap is removed and then, with a fingertip, a consumer pushes inwards a plunger formed at its inner end with a ring of teeth. Again, the plunger remains in the pour spout opening during pouring and thus restricts the through-flow cross-section thereof and, moreover, the use of a finger is unhygienic.
- US-A-4483464 discloses a plastics, similar pour spout fitment .
- GB-A-2210359 discloses a plastics pour spout fitment for a carton the wall structure of which includes a gas barrier layer.
- a gas barrier film is provided across the inner end of a pour spout of the fitment, and the gas barrier layer and the gas barrier film are overlapped or continuous when viewed axially of the fitment, to maintain gas barrier properties for the carton.
- the pour spout is connected via integral bridges to a disc integral with a ringpull inside the pour spout and adhered to the gas barrier film, the intention being that outward pulling of the ringpull breaks the disc away from the pour spout and thus breaks away from the remainder of the gas barrier film the part thereof adhered to the disc.
- opening of the pour spout requires at least a finger to be inserted into the spout to engage the ringpull.
- unscrewing of a screw cap upon the pour spout causes an externally threaded inner skirt of the cap to screw downwards a tubular plunger formed with a ring of teeth at its inner end and guided by keys in longitudinal slots in the inner peripheral surface of the pour spout. Again, the plunger remains in the pour spout after opening and so constricts the through-flow cross- sectional area thereof.
- US-A-5141133 discloses a plurality of differing versions of pour spout fitment, in one of which an axially guided tubular plunger formed with a ring of teeth at its inner end breaks through a synthetic resin film closing a pouring opening through a paperboard wall, and in another version of which a blade at the inner end of a tubular plunger breaks away and pushes aside a disc defined by an annular score in the external surface of a container wall consisting of a paper layer with synthetic resin films laminated to respective opposite sides of the paper layer.
- the plunger remains in its innermost position in the pour spout after opening.
- EP-A-0385603 discloses a pour spout fitment in which a roof panel of a gable-top carton formed from a paper layer provided on respective opposite surfaces with thermoplastic resin layers has a slot of open-loop form punched therethrough, leaving a non-punched portion at the top of the loop.
- a barrier film such as aluminium foil, is attached at the inner surface of the panel so as to cover the slot.
- a pour spout of a pour spout fitment is sealed to the outer surface of the panel around the slot and has connected integrally therewith via frangible bridges a tubular plunger formed at its inner end with teeth. The pour spout is closed by a screw cap. To open the carton, the screw cap is removed and the plunger pressed inwards by a consumer so that the ring of teeth enter the slot and break through the barrier film, causing the panel disc within the slot to turn inwards about the non-punched portion.
- a pour spout fitment comprising a pour spout having a longitudinal axis and adapted to be attached to packaging material, and a plunger in said pour spout and displaceable inwards along said axis relative to said pour spout to displace inwards a portion of said packaging material closing an inner end of the pour spout, characterized in that, following the inward displacement of the plunger, the plunger is displaceable outwards along said axis relative to said pour spout to beyond said pour spout and in that an inner end of said plunger is adapted to be attached to said portion of said packaging material, whereby the outward displacement of said plunger to beyond said pour spout would be accompanied by outward displacement of said portion to beyond said pour spout.
- a pour spout fitment comprising a pour spout having a longitudinal axis and attached to said packaging material, and a plunger in said pour spout and displaceable inwards along said axis relative to said pour spout to displace inwards a portion of said packaging material closing an inner end of the pour spout, characterized in that, following the inward displacement of the plunger, the plunger is displaceable outwards along said axis relative to said pour spout to beyond said pour spout and in that an inner end of said plunger is attached to said portion of said packaging material, whereby the outward displacement of said plunger to beyond said pour spout is accompanied by outward displacement of said portion to beyond said pour spout.
- a method comprising attaching to packaging material a pour spout of a pour spout fitment so that said pour spout extends round a portion of said material, said pour spout having a longitudinal axis, characterized by, prior to said attaching, forming a ring of weakness round said portion, and attaching to the outer surface of said portion a plunger of said pour spout fitment.
- a method comprising providing packaging material to which is attached a pour spout fitment, with a plunger of said fitment being attached to a portion of said material and a pour spout of said fitment being attached to portions of said material around said portion, detaching said portion from said portions by a procedure comprised of displacing said plunger inwardly along an axis of said fitment to cause said plunger to press against said portion, and withdrawing said plunger and thus said portion outwardly from said pour spout.

- Figure 10 is a view of a yet still further modified version of the fitment attached to a wall of a packaging carton, the left-hand side of the Figure showing an axial section through the fitment and the right-hand side of the
- packaging material 2 has attached thereto a pour spout fitment 3 including a pour spout 4 including at its inner end a radially outward flange 5 which is heat-and-pressure welded to the outside surface of the packaging material 2 immediately radially outward of an external, continuous, annulus of weakening 6 in the material 2.
- the annulus of weakening 6 defines a circular disc 8 of the packaging material.
- the packaging material 2 consists of a laminate including inner and outer layers 2a and 2b of a substance, such as LDPE, which is a good barrier to moisture, and an intermediate layer 2c of paperboard.
- the moisture barrier layers 2a and 2b may be extrusion-coated directly onto the inside and outside surfaces of the paperboard during the manufacture of the packaging material 2; however, the fitment 3 finds particular application to a packaging material in which there is, between the layers 2a and 2c, a layer 2d, which is a gas barrier layer, for example a layer of ethylene vinyl alcohol
- the layers 2a, 2b and 2d are tough relative to the paperboard 2c.
- the disc 8 is removed to break the internal barrier layers 2a and 2d to provide a pouring opening.
- the pour spout 4 is provided with external threading 10 for a cap-shaped screw closure 12, which is preferably releasably fixed to the pour spout 4 by some tamper-evident device, for instance by means of an annular band 7 (shown in dotted lines) .
- a plunger 14 Inside the pour spout 4 is arranged co-axially a plunger 14, the inner end of which is secured to the layer 2b of the disc 8, simultaneously with securing of the flange 5 to the annular portion of the layer 2b located round the disc 8.
- securing is by glueing or welding, preferably by hot air and
- the plunger 14 takes the form of a tube 18 which, towards its outer end, is provided with internal left-hand threading 19 co-operating with external left-hand threading 21 provided on a co-axial inner skirt 20 of the screw cap 12.
- the threading 19 and 21 provides a mechanism 17 which converts rotary motion of the cap 12 relative to the spout 4 into the linear inward displacement of the plunger 14. Integral with the plunger 14 and extending
- a resilient ratchet arm 22 which is adapted to co-operate with an internal ratchet tooth 24 integral with the screw cap 12 and arranged on the inside of the screw cap immediately outwardly of the outer end of the plunger 14.
- the arm 22 and the tooth 24 provide a retaining device 23 which assists in retaining the plunger 14 upon the cap 12.
- the plunger 14 can be screwed fully into the bottom of the fitment, using the threading 19,21, since the ratchet tooth 24 and the resilient ratchet arm 22 can easily ride over each other in the particular rotational sense in question. Then the fitment 3 can be attached to the packaging material 2, by heat-and pressure-welding of the flange 5 and the plunger 14 to the material 2.
- the screw cap 12 is unscrewed, so that the plunger 14, which is secured to the outside of the disc 8, will, owing to the left-handed threading 19,21 between the plunger 14 and the skirt 20, initially be displaced purely linarly inwards, to press the disc 8 inwards, until the ratchet tooth 24 abuts the free end of the arm 22, so that relative angular motion between the screw cap 12 and the plunger 14 is prevented.
- the intention behind having purely linearly axially inward movement of the plunger 14 before rotation thereof is to produce initially a compression of the paperboard layer 2c of the disc 8 so that, upon rotation of the plunger 14, there is an optimal transfer of turning forces from the plunger to the innermost barrier layer 2a, to try to ensure wrenching of the portion of the layer 2a in the disc 8 from the carton wall, without delaminating of the disc 8 through the paperboard, which would leave the pouring opening still closed by the layer 2a (and the layer 2d) .
- the version shown in Figure 2 differs from that shown in Figure 1 in that the screw threading 19,21 and the ratchet arrangement 22,24 are omitted and that the inner skirt 20 of the screw cap 12 is provided with external, radial, camming pins 28 engaging in obliquely inclined , closed-ended grooves 26 formed in the inner surface 15 of the plunger 14, the pins 28 and the grooves 26 providing the mechanism 17.
- the camming pins 28 press the plunger 14 purely linearly axially inwards until the camming pins 28 abut the outer ends of the grooves 26, whereupon the plunger 14 is forced to turn with the screw cap 12 so that, if the disc 8 has not already been broken away from the carton wall by the axially inward displacement of the plunger 14, it is wrenched away from the carton wall by the rotation of the plunger 14. Again, it remains attached to the plunger 14 and is removed therewith from the pour spout 4. Owing to the retaining device 23 provided by abutment between the pins 28 and the outer ends of the grooves 26, the plunger 14 remains connected to the cap 12.
- FIG. 3 differs from that shown in Figure 2 in that the inner skirt 20 of the screw cap 12 is arranged radially outwards of the plunger 14 attached to the disc 8, and in that the plunger 14 has diametrically opposite, external, camming pins 32 engaged in obliquely inclined, closed-ended slots 34 through the skirt 20.
- unscrewing of the cap 12 causes the plunger 14 initially to be displaced purely linearly axially inwards until the outer ends of the slot 34 come to abut the pins 32, whereupon the plunger 14 is forced to follow the turning of the cap 12, so detatching the disc 8 from the carton wall and removing it together with the cap 12 and the plunger 14.
- the outer end of the plunger 14 includes two end camming surfaces 40 and 42 arranged at an angular pitch of 180° about the axis A of the fitment.
- Each of the camming surfaces 40 and 42 is of a radial width of at least one-quarter of the external diameter of the plunger 14, so as to give reliable operation in spite of manufacturing tolerances and any minor manufacturing defects.
- Each camming surface 40,42 terminates at its outer end in an abutment 44.
- the camming surfaces (46) and the abutments (48) are also of a radial width substantially equal to that of the camming surfaces 40 and 42 and the abutments (44) and for the same reasons.
- the camming surfaces provide the mechanism 17.
- the camming surfaces and the abutments 40 to 48 co-operate, initially to press the plunger 14 purely linearly axially inwards, whereupon the groove 50 disengages from the rib 52, until the abutments (44 and 48) come into contact with each other, so that the plunger 14 is forced to turn with the cap 12, to detach the disc 8 from the carton wall if the disc has not already been detached by the linearly inward displacement of the plunger 14.
- the disc 8 is then removed with the plunger 14 and the cap 12.
- the plunger 14 is prevented from leaving the skirt 20 by engagement of the rib 52 against a shoulder 54 part-way along the external surface of the plunger 14.
- the rib 52 and the shoulder 54 provide the retaining device 23.
- the weakening 6 may advantageously not be an annular partial-depth cut, but may be a series of arcuate, partial-depth cuts 6a arranged end- to-end and spaced apart from each other by non-cut bridges 6b.
- the version shown in Figure 8 differs quite considerably from any of the previous versions. It again includes a screw cap 12 screwed onto a pour spout 4, but in this version the plunger 14 takes the form of a ring 60 which is connected by curved links, in this example three curved links 62, to an outer ring 64 attached by any appropriate retaining device 23, for example by catches 66 shown, to the inside surface of the outer end of the cap 12.
- the links 62 which provide the mechanism 17 and are of a helically curved form substantially co-axial with the spout 4 have their inner ends connected by integrally moulded hinges 68 to the ring 60 and their upper ends connected by integrally moulded hinges 70 to the ring 64.
- ratchet teeth 69 which co-operate with an equal number of ratchet teeth 71 at the inside of, and integral with, the cap 12 to allow screwing of the cap 12 onto the spout 4 and thus relative to the ring 64 but preventing more than a small degree of turning of the cap 12 relative to the ring 64 in the unscrewing sense.
- the ring 60 is integrally moulded with the pour spout 4 by way of frangible bridges 72 which serve to retain the ring 60 in an axial position ready for heat-and pressure-sealing to the packaging material.
- the screw cap 12 is formed internally with a central boss 80 which provides the catches 66 through having externally at its inner end a rib 82 interrupted by slots 84 to allow a non-integral skirt 20 to be snap-fitted over and retained on the boss 80.
- the skirt 20 is provided with the ratchet teeth 69 to co-operate with the ratchet teeth 71 of the cap 12.
- the skirt 20 is encircled by a plunger 14 which has an internal shoulder 90 and is connected to the skirt 20 by way of the threading 19,21, and integrally connected to the pour spout 4 by way of the bridges 72.
- the skirt 20 is formed with a radially outwardly directed annular flange 92.
- the effect of the threading 19,21 is to push the plunger 14 purely linearly axially inwards until the shoulder 90 abuts the flange 92, whereupon the plunger 14 is forced to rotate with the skirt 20 and the cap 12.
- the axially inward movement of the plunger 14 of course breaks the bridges 72 and detaches the disc from the carton wall. Once the cap 12 is free from the pour spout 4, it can be removed together with the skirt 20, the plunger 14 and the disc.
- the version shown in Figure 10 differs significantly from any of the previous versions, in that the purely linearly axially inward displacement of the plunger 14 is not produced by unscrewing of the screw cap 12, but by axially inward manual pressure on the outer end of the plunger 14.
- the plunger 14 is in the form of a rod having radial flanges 100 and 102 at the inner and outer ends thereof.
- the flange 100 is adhered face-to-face to the disc 8, whilst the flange 102 is located axially outwards of the cap 12 with which it
- the cap 12 includes an inner skirt 20 in which the rod-form part of the plunger 14 is a sliding fit.
- the band 104 is torn away, manual pressure is applied axially inwards to the outer end of the plunger 14 to detach the disc 8 from the carton wall, the axially inward movement of the plunger 14 relative to the cap 12 being limited by a retaining device 23 in the form of abutment of the flange 102 against the outside of the cap 12, and then the cap is unscrewed and removed from the pour spout 4, taking with it the plunger 14 and the disc 8.
- packaging fields are not only those in which drinkable foods, such as milk, fruit juice and wine are packaged, particularly aseptically, but also to packaging fields in which other products, for example pharmaceutical products, are packaged.
